This guide shows how to delete an Exchange Online mailbox, without deleting associated user account in Azure AD.<\/h3>\n

This can be verry usefull if you are about to setup a Hybrid environment<\/span><\/span> whit your on-premises Mailserver.<\/h3>\n

If you delete the Azure AD user account then, obviously, mailbox is removed, but maybe we don’t want to do that, since users will lose all onedrive, teams data etc.<\/h3>\n

 <\/p>\n

If you navigate to; https:\/\/admin.exchange.microsoft.com\/#\/mailboxes<\/strong><\/a> you will see the mailboxes i 365<\/p>\n

Here we see Anders<\/strong> have a mailbox in 365<\/p>\n

\"\"<\/a><\/p>\n

Remove the users Exchange Online License<\/h2>\n

Go to https:\/\/admin.microsoft.com\/#\/users<\/strong><\/a> and find the user (let’s take Anders Again) note Anders is currently<\/span> not synced whit the local AD<\/span><\/span>\u00a0<\/strong><\/p>\n

\"\"<\/a><\/p>\n

Click on Licenses and Apps\u00a0<\/strong>and click on Apps<\/strong><\/p>\n

\"\"<\/a><\/p>\n

Remove the Exchange Online license<\/strong> and click Save<\/strong><\/p>\n

\"\"<\/a><\/p>\n

if we look back at https:\/\/admin.exchange.microsoft.com\/#\/mailboxes<\/a><\/strong>, we see the mailbox is now soft deleted (but not hard deleted, so if we give the user the Exchange Online license back, the mailbox will just come back again)<\/em><\/p>\n

\"\"<\/a><\/p>\n

Connect to exchange online powershell<\/h2>\n

Now we have to purge the soft deleted mailbox<\/p>\n

Run this command;<\/strong><\/p>\n

Set-User user@domain.com -PermanentlyClearPreviousMailboxInfo<\/pre>\n
And confirm to delete the mailbox<\/strong><\/p>\n
Y<\/pre>\n
\"\"<\/a><\/p>\n
Move the user back to an synced OU (optional<\/span><\/span>)<\/h2>\n
Move the user to an OU in your local active directory that is your AD Connect sync scope, and make a fresh sync or wait 30mins (Start-ADSyncSyncCycle -PolicyType delta)<\/p>\n
Now Anders is AD Synced<\/p>\n
\"\"<\/a><\/p>\n
Give user the Exchange Online License back<\/h2>\n
Give Anders back his Exchange Online license<\/strong>, and click save<\/strong><\/p>\n
\"\"<\/a><\/p>\n
Lets take a look at Anders mailbox again. Now it shows This user’s local mailbox has not been migrated to Exchange Online.<\/span> The Exchange Online mailbox is available when the migration is complete<\/span><\/span>\u00a0<\/strong><\/p>\n
